Status
Active

Summary

// what this is
Talk-A-Phone Co is registered to MAC prefix 001EEB and 1 more in the IEEE OUI database. When a device's MAC address begins with 001EEB, that block was registered by Talk-A-Phone Co — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Two independent OUI assignments at two Illinois addresses, one matching the company's current headquarters, and a documented networked product line together support treating this as a substantive, active vendor rather than a shell registration.

About this vendor.

Updated  ·  Confidence: Likely  ·  7 sources  ·  How this page is checked

A MAC address beginning with 00:1E:EB or DC:09:14 belongs to Talk-A-Phone Co., a manufacturer of networked emergency communication hardware -- blue-light emergency phones, elevator and area-of-refuge phones, and mass-notification speakers -- typically deployed as IP-based access-control and life-safety endpoints in parking structures, campuses, and transit facilities.

Talk-A-Phone holds two separate IEEE MA-L (/24) OUI assignments: 00:1E:EB, registered to an address in Chicago, IL, and DC:09:14, registered to 7530 N. Natchez Ave., Niles, IL -- an exact match to the company's current headquarters as published on its own website. No MA-M or MA-S entries were found for the vendor.

The company's product line is networked hardware: SIP-capable emergency call stations, elevator and area-of-refuge phones, WEBS mass-notification speakers, and access-control intercoms, consistent with holding Ethernet-interface OUI blocks. Deployments are reported at colleges, parking structures, medical centers, correctional facilities, and transit centers, sold both direct and through security integrators.

No CVE or public security advisory naming Talk-A-Phone Co. was found as of a September 2026 search across NVD, CVE.org-adjacent sources, and general vendor-advisory listings. This is recorded as a sourced negative rather than a claim of a clean security record. IEEE publishes no registration or last-updated date for either OUI block; both fields stay Unknown here.
